<p>The board design, preferably for boards for traffic and non-traffic signs solves the problem of its simple installation, removal and replacement while featuring a simple and compact base construction. The board frame (9) consists of a pair of border profiles (10) and a pair of terminal profiles (13), which are located face to face. The board (9) is inserted into the grooves (18) of both border profiles (10), while their grooves (19) feature straight-lined movable fixing elements (11) of identical shape with screws (16), by which the board (9) with frame, is attached to the auxiliary supports (8) via semi-flanges (12). The border profiles (10) and linking elements (11) are of identical cross section and dimensions, while the latter are at a right angle inserted into their grooves (19) so that with their longer protuberance (26) they fit the back side of the board (9). The auxiliary supports (8) are inserted via openings (23) into the cross bar (2) and are fixed to it with the help of a flange (14) and screws (20).</p> |
